Business Services no longer publishes a direct email
The Idaho SOS Business Services Division now routes inquiries through a web contact form rather than a published business@sos.idaho.gov mailbox. Use the Business Services contact form above, or call (208) 334-2301 (business filings) or (208) 334-3191 (UCC & liens) directly. The office's general email, secretary@sos.idaho.gov, still reaches the main administration line.
Entity formation and filing fees
Idaho publishes per-form base filing fees on its Business Forms page; paper submissions add a flat $20 manual processing fee on top of the base fee (Idaho Code §30-21-214). Filing online through SOSBiz charges only the base fee and skips the manual processing surcharge. Verify current amounts at sos.idaho.gov/business-forms or in the SOSBiz filing wizard before filing.
| Filing | Fee (online / paper) |
|---|---|
| Domestic LLC — Certificate of Organization | $100 online / $120 paper (+$20 manual fee) |
| Domestic For-Profit Corporation — Articles of Incorporation (General Business) | $100 online / $120 paper (+$20 manual fee) |

| Foreign Entity — Registration Statement | $100 online / $120 paper (+$20 manual fee) |
| Amendment (LLC, corporation, or foreign registration) | $30 online / $50 paper (+$20 manual fee) |
| Name Reservation (4 months) | $20 online / $40 paper (+$20 manual fee) |
| Dissolution / Statement of Dissolution | No base fee online / $20 manual fee if filed on paper |

Idaho annual reports carry no filing fee, online or by mail — a notable exception to most other states. Businesses that file frequently can open a Tyler Idaho subscriber account ($95 annual subscription fee) for consolidated monthly invoicing instead of paying per-transaction card fees; this replaced the prior "Access Idaho" payment-account branding. Checks or money orders payable to "Idaho Secretary of State" avoid the card processing fee entirely.
